YouTube: Mathematical physicist, pioneering studies in chaos theory led to Feigenbaum constants.

Quotable quote: “It’s a fraud to have named the subject ‘chaos,'” he said, a term coined in 1975 by mathematician James Yorke.

Dear Prof. Dr. Mitchell J. Feigenbaum:

Unless it is just silliness, I will be reviewing the Feigenbaum constants with our high school math club, and once refined a little, then with three high school geometry classes.

Our assumption is that your constants can help us anticipate the tensions between quantum theory and relativity, and between linear and non-linear transformations.

Are we improperly using your constants?

Thank you.

Most sincerely,

Bruce

Dear Prof. Dr. Mitchell Feigenbaum:

We discovered your work through Kepler, spheres, close cubic packing and base-2 notation. Then, we included the Feigenbaum constants within our listings of the top ten numbers and number groups in the universe. Our references to your work are here:
https://81018.com/number/#4
https://81018.com/number/#7

Ours is a rather odd view of a highly-integrated universe created in around 202 base-2 notations from the Planck base units, i.e. Planck Time to the Age of the Universe. It all started in our high school geometry classes when we didn’t stop dividing in half the tetrahedron and then octahedron within it. https://81018.com/home/

Would you advise us? Is there any possibility that we aren’t wasting our time? Thank you.

Warm regards,
-Bruce
